Title: Improvements in radio receivers for direction-finding
IPC: C09B23/04
Filed: 1940-09-02
Abstract: 569,303. Directive wireless systems. RADIO TRANSMISSION EQUIPMENT, Ltd., and BAILEY, C. E. G. Sept. 2, 1940, No. 13758. [Class 40 (v)] Relates to directionfinding receivers of the kind employing a plurality of directive aerials switched or modulated at a lower frequency and giving a direct bearing indication on a cathoderay tube. The aerials W, E and N, S shown as Adcock pairs are connected to modulators M1, M1<1>, M2, M2<1> at which they are modulated or switched at angular frequencies p1, p2 respectively. The pair W, E are arranged to feed modulators M1, M1<1> in phase quadrature, a phase-shifting device P1 being interposed before the modulator M1<1>. The modulating voltage p1 is also fed to M1, M1<1> in phase quadrature with the result that a single side-band is produced when the outputs of M1, M1<1> are joined. The aerials NS are similarly connected to modulators M2, M2<1> which are modulated at frequency p2 to produce a single side-band. An omni-directional aerial C1 adds carrier in the desired phase to the two side-bands and the mixture is fed to a single amplifier A1 and detector D. Filters select the frequencies p1, p2 from the detector output and pass them respectively to modulators M3, M4 which are also fed with frequencies p2, p1 so that each modulator produces a frequency p3 equal to the sum of p1 and p2. The respective outputs are filtered and applied to the deflecting plates of a cathode-ray tube T which shows the direction of the incoming wave. A sense indication may be obtained by applying the frequency p3 in suitable phase to a control electrode of the tube. Modulation of the received aerial currents is preferably effected by a rotary switching device, shown in Fig. 2. Quadrature phases of the input from aerials W, E may be applied to brushes Kl, K2, L1, L2 bearing on segments B1, B2 rotating at angular velocity p1, side-band output being taken to the amplifier A from brushes G, H bearing on slip rings A, C connected to the segments B1, B2. The other aerial pair N, S feeds a similar modulating-switch rotating at angular velocity p2. The angular frequency p1 for applying to the modulator M4 is picked up by brushes Q, R and slip rings X, Y connected across an armature D rotating with the shaft carrying the segments B 1 in a field F at angular velocity p1. The rates between the frequencies p1 and p2 may be maintained by gearing the respective shafts to each other, or by using only one shaft with different numbers of'commutator segments and alternator poles. The modulators M3, M4 may be of electromechanical type, and may be followed by valve amplifiers preferably of the kind described in Specification 536,538. Spaced loop aerials may replace the Adcock pairs. Specifications 490,940 and 496,239 are referred to.

Title: Improvements in variable speed transmission systems for motor vehicles
IPC: F16D67/00
Filed: 1961-04-19
Abstract: 919,277. Change speed gear. TATRA, NARODNI PODNIK. April 19, 1961 [April 21, 1960], No. 14212/61. Class 80 (2). [Also in Group XXXIV] An hydromechanical variable speed epicyclic gear serially arranged following, and permitting gear change under load in, a two or more speed change speed gear in a motor vehicle comprises an hydrodynamic torque converter or, as shown, fluid coupling having an impeller C, a turbine T, and an epicyclic gear D in which a planet carrier R connected to an output shaft II of the change speed gear has planets 2 meshing a sun 1 connected to the impeller C and a ring 3 connected to the turbine T and to an output shaft III of the system. To provide a two-speed gear the sun 1 may be braked under load at B. The sun 1 and ring 3 may be clutched, and released under load, or permanently connected to the impeller C and the turbine T respectively, in which latter case the fluid coupling has provision for rapid filling and emptying. The clutch between the sun 1 and the impeller C may comprise a freewheel which permits the impeller to overrun the sun, however, this precludes hydrodynamic braking and, in certain gears, engine braking. Release of the brake B and filling the fluid coupling, the sun 1 and ring 3 being connected to the impeller C and the turbine T respectively, provides a splittorque direct drive. Applying the brake B and emptying the fluid coupling or disconnecting the impeller or turbine from the sun or ring respectively, provides mechanical overdrive. Hydrodynamic braking is by simultaneous engagement of the brake B and filling of the fluid coupling. The combination of the epicyclic gear with a two forward speed and one reverse change speed gear as shown provides four forward speeds and two reverse, although by suitable choice of ratios, dispensing with second gear, three forward speeds may be obtained having first and second with the split-torque drive and a high gear with the mechanical overdrive. As shown, the epicyclic change speed gear comprises sunring planet trains 8, 7, 9 and 4, 5, 6 having the sun 8 braked at B1 for low gear, and clutched to input at S1 for solid 1/1 high gear, and a common carrier P braked at B2 for reverse. In Fig. 2 (not shown), a parallel shaft twospeed change speed gear A is positioned rearwards of the fluid coupling for rear engine mounting, and comprises constant mesh gears, those on its input shaft being selectively clutched thereto.
